Summary: This paper experimentally evaluates the viscosity and thermal conductivity of Fe3O4/water nanofluid and proposes an estimation model using an artificial neural network. The results indicate that the volume fraction of nanoparticles and temperature have a direct relationship with the thermal conductivity coefficient of nanofluids, while the viscosity of the nanofluid decreases with the decrease in volume fraction of nanoparticles and increases with the decrease in temperature. The neural network shows fewer errors and higher accuracy in predicting the viscosity and thermal conductivity of nanofluids.

Summary: This article analyzes the mixed convective hybrid nanofluid flow over a shrinking cylinder in a porous medium, taking into account the presence of a magnetic field. The study finds that the skin friction coefficient and Nusselt number increase significantly with the increase in mixed convection parameter, magnetic field parameter, and porosity parameter. The study also reveals that the boundary layer separation is delayed due to higher values of these parameters, as well as the curvature parameter and volume fractions of the nanoparticles.

Summary: Hybrid nanofluids, particularly those containing graphene oxide (GO) and iron oxide (Fe3O4), have been shown to enhance physical strength, thermal conductivity, and mechanical resistance in thermodynamic systems. This study investigates the thermal and magnetic properties of both pure nanofluid GO/engine oil (EO) and hybrid nanofluid GO-Fe3O4/EO under the influence of induced and applied magnetic fields. The reduction in induced magnetic field and fluid velocity is found to be associated with an increase in magnetic Prandtl number and induced magnetic field parameter. Additionally, the hybrid nanofluid GO-Fe3O4/EO demonstrates thermal stability and corrosion prevention.

Summary: This study investigates the flow of hybrid nanofluid in a porous medium in a non-axisymmetric stagnation point region. The results show that the friction factor increases with the hybrid nanoparticles and porous medium parameter, while the hybrid nanoparticles enhance the heat transfer rate but the porous medium parameter has the opposite effect. Additionally, the shear-to-strain-rate ratio at which zero friction occurs on the wall is also determined.

Summary: In this study, the MHD water-based nanofluid flow past an impulsively started infinite vertical plate embedded in a porous medium is investigated, considering ramped velocity and concentration, as well as the presence of Hall effect, thermal radiation, chemical reaction, heat source/sink, and thermal diffusion. The governing equations are solved using the Laplace transform method, and the effects of various embedded parameters on velocity, temperature, and concentration profiles are analyzed through graphical interpretation. The variations of the Nusselt number, Sherwood number, and skin friction are also studied. It is found that higher nanoparticle volume fractions lead to reduced primary and secondary velocities and concentration, while increasing the temperature. Thermal diffusion increases the fluid concentration, and the rate of momentum transfer decreases with an increase in the Hall current parameter.

Summary: This paper examines the mechanism of radiative Walter's B nanofluid on a rotational cone under magnetic regime, including the theoretical and practical implications of time-dependent fluid flow caused by cone rotation in engineering and applied sciences, as well as the characteristics of thermophoresis, Brownian motion, and chemical reactions. Self-similar solutions are obtained and the numerical result of a reduced nonlinear system is obtained using the Runge-Kutta-Fehlberg fourth-fifth procedure. Comparisons with previously published material are made to verify the outcome. The conflicting influences of the Brownian motion parameter on heat and mass transfer rates, as well as temperature and concentration fields, are found. The presence of chemical reactions may be more beneficial in developing reaction processes.

Summary: This study numerically examines the influence of various geometric parameters on the thermal performance of a novel W-shaped porous cavity undergoing hybrid nanofluid-based magnetohydrodynamic mixed convection. The results show that an increase in the bottom undulation height improves the thermal energy transfer despite the reduction of fluid volume. The overall thermal energy transport is improved by increasing Reynolds number, Richardson number, and Darcy number, while it is suppressed by increasing Hartmann number.
